Now I am wanting to create a first round seeded draw based on the imported performances. I cannot find a method for doing this.

Is this possible?

Thanks,
Richard

Yes it is possible:
1) if not done by wizard, you need to create an "individual classification" based on "performance round" for each event
2) in "Make starting list", you choose the event, then click on button "From classifications" and choose the performance based classification you have created.
